“…Furthermore, we are now acknowledging that 'one model fits all' is not appropriate for communities and ecosystems due to the complexity of the system (Hobbs et al 2007). However, the scientific knowledge in this field is also inadequate, particularly in tropical montane forests, where scientific studies about the effects and the ecological consequences of disturbances at high-elevation are still scant (Horn et al 2001).…”

“…La pérdida de los bosques tropicales de la República Dominicana es de más de 20,000 ha/año, y en las zonas afectadas por fuegos forestales y la extracción de madera, la tasa es de alrededor de 60,000 ha/año (Peña et al 2005). La fragmentación de los ecosistemas afecta a la flora y la diversidad de fauna por lo que resulta importante realizar estudios de los ecosistemas forestales de la República Dominicana, en este caso las masas forestales de Pinus occidentalis, para profundizar nuestra comprensión de la diversidad y también para establecer la conservación y las normas de gestión (Horn et al 2001). …”

Resumen: La gran biodiversidad de especies de plantas en la isla La Española, hace conveniente la elaboración de trabajos que permitan identificar las familias, géneros y especies, a partir de diversos caracteres, como los anatómicos. En la República Dominicana se carece de investigaciones sobre las semillas de las especies endémicas. Es importante profundizar en estudios morfológicos y anatómicos de las semillas de nuestras especies y emplearlas con diferentes fines, como orientación taxonómica, conocer más sobre su ecología, entre otros. En nuestro trabajo tratamos de utilizar un carácter relevante de Pinus occidentalis, como es su semilla. El presente estudio nos permite conocer sobre la superficie de la semilla de Pinus occidentalis, pues la morfología de la semilla juega un papel importante en la dispersión de la especie.

“…Information on the effects of fire on vegetation, including pine survivorship and patterns and rates of postfire recovery of pines and other taxa, is needed for management but presently limited. Horn et al (2001) investigated a 2‐yr‐old burn site at 2400 m elevation in Juan B. Peréz Rancier National Park (JPRNP; Fig. 1) and found evidence of pine regeneration, and high rates of resprouting by most shrub species.…”

“…Research on fire effects in the Dominican highlands provides an opportunity to add to understanding of postfire dynamics in tropical upland ecosystems more generally. The Dominican sites overlap significantly in floristic composition at the family and generic level with grass‐ and shrub‐dominated ecosystems in the highlands of southern Costa Rica, the northern Andes, and southeastern Brazil (Horn et al 2001). Though lacking pine, these páramo and páramo‐like ecosystems also have been influenced by fire for millennia (Horn 1993, Hansen & Rodbell 1995, League & Horn 2000, Behling et al 2007).…”

We surveyed postfire vegetation at five sites at high elevations (> 2000 m) in the Cordillera Central, Dominican Republic. Highlands of the Cordillera Central are dominated by a single pine species, Pinus occidentalis, but plant communities are rich with endemics and conservation and fire management efforts in these systems are ongoing. The burns were 2–7 yr in age and had consumed nearly all shrub crowns. Pines suffered high mortality (> 50%, all sites combined), but shrubs resprouted at high rates (88%, N= 957) after fire. All shrub taxa produced basal resprouts; eight of 11 shrub taxa measured had resprouting rates > 90 percent, while Baccharis myrsinites had the lowest (56%). Most taxa grew to prefire height quickly (within 5–7 yr), with regrowth of stem diameters lagging behind. Patterns and rates of shrub recovery resembled those documented in high elevation shrublands in Costa Rica and Brazil. Pinus occidentalis does not resprout, but larger individuals can survive fire. Survival increases dramatically when trees attain > 13‐cm dbh, when bark becomes thick enough to protect cambial tissue. Overall, pines are regenerating much more slowly than shrubs, but seedling establishment varied considerably between sites. Frequent fires may cause a decline in pines and an increase in shrub‐ or grass‐dominated communities. Succession in these high elevation fire‐dependent pine forests favors taxa already present in the preburn vegetation, with woody composition changing little after fire, in contrast to lower‐elevation cloud forest, where postfire vegetation has been shown to bear little resemblance to mature forest even after several years.
